With the development of an immersion probe ASTECH meets the frequent requirements for in-situ color measurement in liquids. In chemical industry, color and color saturation of liquids is often an indicator for the concentration of a solution to be determined or indicates the state of a chemical reaction. The same applies to the analysis of water, cleaning fluids or solvents. Areas of application are, for example, the detection of dye residuals, active oxygen or suspended particles. A tee piece with 3/4“ thread connections makes it easy to connect the probe in such applications. The immersion probe is connected to a color sensor of the CROMLAVIEW® color sensor family by means of a temperature stable (up to 180 ° C) and liquid-tight reflex mode fiber cable. The combination of an adjustable measuring length (0-10mm), a 12-bit control of the illumination LED, as well as a 1:800 input sensitivity of the sensor ensures a large dynamic range.
